Other AbstractThe invention belongs to the field of friction stir welding and particularly relates to a welding with trailing extrusion device for friction stir welding and a welding with trailing extrusion method thereof. The device comprises a supporting base, a supporting arm, a force applying spring and an extruding wheel, wherein the supporting base is connected with a static shaft sleeve of a friction stir welder through a bolt, so that the device is welded to the welder; the supporting arm is L-shaped; the supporting arm and the force applying spring are connected with the supporting base through pin shafts; the extruding wheel is connected to the tail end of the L-shaped supporting arm, and moves downwards through a main shaft to stress a to-be-welded workpiece. When the welding with trailing extrusion device is used for welding a metal plate which is relatively large or small in width, the manufacturing cost of a clamping tool can be effectively reduced, the process of mounting the clamping tool before welding is simplified, the welding space of a welding tool is increased, high-quality formation of a welding seam is guaranteed, and the application range of friction stir welding technology is widened.
